KNITTIINGMACHINE.

SPECIFICATION forming part 0f Letters Patent NO. 480,938, dated August16, 1892.

Application filed March 19, 1892. Serial No; 425,613. (No model.)

To all whom it may concern:

Be it known that I, EDISON ELsWoR'rH RAN- DALL, a citizen of the UnitedStates, residing at West Winsted, in the county of Litchfield and Stateof Connecticut, have invented a new and useful Knitting-Machine, ofwhich the following is a specication.

This invention relates to certain new and useful improvements inknitting-machines and has special reference to circular-knittingmachines provided with means for preventing the jack-sinkers orloop-holders from Wearing or raising out of their proper position.

The object of the invention is to cause the stitches or loops to retaintheir proper places on the needles, and thereby prevent imperfect workor dropped stitches.

To this end the invention consists of the construction and arrangementof parts, as will be more fully hereinafter described, and pointed outin the claims.

In the drawings, Figure 1 is a perspective View of acircular-knitting-machine cylinder with the jack-sinkers in positionthereon, the cam-cylinder being removed and the needlecylinder aloneillustrated. Fig. 2 is a trans- Verse vertical section ot' the partsrepresented by Fig. l. Fig. 3 is a top plan View of the same. Fig. 4. isa detail perspective viewV of the improved attachmentshown disconnected.

Referring to the drawings, A designates the needle cylinder with needlegrooves B and having jack-sinkers or loop-holders C mounted in the upperportion thereof in a suitable frame, as is usual in this class ofdevices, said jack-sinkers or loop-holders C being provided with armsC', projecting radially into the said needle-cylinder, all of which isof well-known construction and arrangement.

The present improvement comprises an annular disk or ring D, Which isnormally located on the arms C of the jack-sinkers or loop-holders C.Inr connection with the cylinder A is a rib or ring E, to which aresecured springs F, attached at their upper ends to said ring or disk D.When this rib or ring E is made separable from the cylinder, it may besecured to cylinders now in use, together with the remaining portion ofthe attachment, and it will be understood that the number of springs F,connecting the ring or disk D ers or loop-holders C and permit thelatter to 6o be removed or raised, if desired. While the said ring ordisk D is in position on the said arms C the said jack-sinkers orloop-holders are held in their proper positions and prevented fromhaving movement other than the I movement thereof inward and outwardfrom the cylinder in a horizontal plane, as is usual. The Wear on thesaid jack-sinkers or loopholders is materially reduced, and by the useof the improved attachment the stitches or 7o loops as formed are keptin their proper places on the needles, thereby avoiding imperfect Workor drop-stitches, as hereinbefore set forth.

The advantage .and utility of the improved attachment heretofore setforth are readily apparent to those skilled in the art, and owing to thesimplicity of the construction and arrangement of the parts it may bereadily made and applied Without materially increas- 8o ing the cost ofknitting-machines of this class or changing the structure thereof in theleast.

The use of the device heretofore explained in connection with thesinkers and cylinder does not in the least retard the usual function ofthe sinkers in connection with cylinders of this class or the formationof the fabric, as the location of the device is such as not to interferewith the movement of the sinkers or of the proper feeding away of the 9ofabric formed and downward movement thereof through the cylinder bymeans of the usual attached weight. The advantage gained by the use ofthe ring or disk is that the fabric is'sustained a greater length oftime in a 95 horizontal position to cause the loops to be more perfectlyformed.

Having thus described my invention, what I claim as new isl. In acircular-knitting machine, the comroo bination of a cylinder having jack-sinkers or loop-holders thereon and a disk or ring bear- The springsconnecting 55 ing on parts of said jacksinkers or loopholders andlocated over the opening through said cylinder, substantially asdescribed.

2. The combination of a knitting-machine cyllnder having jack-sinkers orloop-holders 1n connection therewith and a ring or disk loosely andremovably engaging said jackslnkers or loop-holders, substantially vasdescribed.

3. In a circular-knitting machine, the comi bination of a cylinderhaving jack-sinkers or loop-holders thereon, a disk or ring looselybearing on parts of said jack-sinkers or loopholders, and springs forholding said disk or ring in proper position, substantially asdescribed.
